No, not the type of #2 you're thinking (although we look back on some of our original design ideas and think of it that way) but the second functional prototype Shelf installed in a Scion xD. We got smart here and added buttons, but thought that having them on the side was best. After the bottom lip of the Shelf broke off (while reaching for the turn-signal) we started looking for ways to reinforce the lip when we had an A-Ha! moment and placed the buttons on the bottom instead. And for the record, pretty sure it was my idea

It's like an ugly child that only a parent could love... And I do!!! That prototype was an awesome leap from a napkin sketch to something we could use and evaluate as you said Thomas and launch the ideas that has got us to the interface we have now...
